I've always heard that bears can smell, and are attracted the batteries in the cameras, and that's why they go after them. This year I'm leaning towards they prefer a certain brand over others. We have 10 cameras out with different brands of batteries 8-10 feet high. Out of Energizer, Duracell, and a third brand that I can't think of right now, the hands down winner are the Duracells. Bears love em! Only the cameras that have them are constantly attacked by bears. Coincidence? Maybe. Are Duracells a stronger battery? IDK. All I know is the cameras with Duracell batteries are getting all of booboos attention.
